Chapter 1: The Future of Fabric

Recent advancements in robotics have led to the creation of "Robotic Fabric," a groundbreaking material with the ability to alter its shape and stiffness on command. This novel concept is gaining traction in the realm of soft robotics, which, despite being relatively new, already promises diverse applications. For instance, NASA is exploring the use of this technology for robotic missions to Titan, one of Saturn's moons, allowing vehicles to navigate challenging terrains with ease.

In another notable development earlier this year, Stanford researchers unveiled a soft robot designed to enhance human capabilities through its efficiency, safety, and flexible design. These innovations illustrate the exciting potential of soft robotics.

Now, a team led by Professor Rebecca Kramer-Bottiglio has designed a lightweight, flexible, and breathable robotic fabric that occupies minimal storage space. This fabric can transform from a flat, conventional material into a sturdy, load-bearing structure.

“Our Field’s metal-epoxy composite can become as flexible as latex rubber or as stiff as hard acrylic, over 1,000 times more rigid, just by heating it up or cooling it down. Long fibers of this material can be sewn onto a fabric to give it a supportive skeleton that we can turn on and off.”

To integrate these capabilities into a standard fabric, the research team converted functional materials into fiber form, seamlessly merging them with the fabric while retaining their beneficial properties. The Field’s metal-epoxy composite exhibits remarkable adaptability, becoming as flexible as latex rubber or as rigid as hard acrylic based on temperature changes. It melts at a relatively low temperature of 62 °C (144 °F), allowing for easy manipulation before being cooled to lock into a specific shape.

The video titled "Robotic fibers can make breath-monitoring garments" explores the innovative applications of this advanced textile technology.

The team’s research culminated in the development of robotic fabric capable of not only changing shape but also supporting weight—holding up to 50 grams (1.8 ounces). This fabric incorporates sensors made from a non-toxic conductive ink based on a Pickering emulsion, which were painted directly onto the material to enable it to detect both internal and external changes and react accordingly.

To facilitate shape changes, the researchers employed shape-memory alloys (SMA) that can be programmed to revert to a predetermined shape after deformation. SMA wires were flattened into ribbons to assist the fabric in returning to its original flat form.

The researchers envision utilizing this technology for applications such as self-deploying tents, robotic parachutes, and assistive clothing. Funded by the U.S. Air Force, their comprehensive research findings were published in the Proceedings of the National Academy of Sciences.
